POWDER-DISTRIBUTER.

Specification of Letters Patent.

Patented June 30, 1908.

Application filed February 17, 1908. Serial No. 416,352.

' To all whom "it may concern:

Be it known that I, CRAWFORD D. HOLT, a

citizen of the United States, residing at Murray, in the county of Galloway and State of Kentucky, have invented a new and useful Powder-Distributer, of which the following is a specification. This invention has relation to powder distributers and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide a distributor of the character indicated which is provided with a double bellows adapted to supply a continuous blast of air for projecting powder. A rece tacle for holding powder is mounted upon t e bellows. A discharge outlet tube which is rectangular in cross section is attached to the bellows and is located over the air outlet thereof. Said tube is provided in its bottom with a short depression. A funnel depends from the said receptacle and bears at its lower end upon the bottom of the tube. The lower end of the funnel is located directly over said depression whereby space is provided through which the powder may pass from the funnel into the tube.

A further object of the invention is to provide a tube of the character indicated with a discharge nozzle of peculiar configuration which is adapted to scatter the powder laterally as it is discharged therefrom.

In the accompanying drawing: Figure 1 is an edge elevation of the distributor with parts in section. Fig. 2 is a transverse sectional view of the same out on the line 2, 2 of Fig. 1 and Fig. 3 is a plan view of the discharge end of the tube.

The distributer consists of the double bellows 1 the opposite sides of which are separated by the central partition 2. The hinged side of each bellows member is provided with the usual valved air inlet 3. The link 4 connects the edges of the hinged sides of the bellows members together. The block 5 is mounted at the end of the partition 2 and is provided with a valved passage 6. The end of the partition 2 is recessed as at 7 and the ends of the said recess are closed by the perforated plates 8. The valve disk 9 is located in the recess 7 but is less in transverse thickness than the depth of the said recess. The inner end of the tube 10 is attached to the block 5 and is located over the outlet of the passage 6 thereof. Said tube is rectangular in cross section and has its longer transverse axis' horizontally disposed. The receptacle 11 is mounted upon the block 5 and is provided with a suitable cover 12. The funnel 13 depends from the receptacle 11 and passes through the top side of the tube 10. The lower end of said funnel rests upon the lower side of the said tube. The bottom or lower side of the tube 10 is provided with a short concaved groove or depression 14 which is located directly under the lower end of the funnel 13. The top of the tube 10 is provided with a downwardly inclined portion 15 which is disposed from the upper side of the block 5 toward the lower end of the funnel 13 and the groove 14 and is adapted to deflect air toward the said groove. The discharge end of the tube 10 is flattened as at 16 and the discharge outlet is substantially V-shaped in plan.

The receptacle 11 is filled with powder which passes down through the funnel 13 and enters the groove 14. As the bellows 1 are operated a continuous blast of air passes through the passage 6 and is deflected by the section 15 of the tube 10 against the lower end of the funnel 13 and into the groove 14. Thus the powder is caught up by the blast and is carried along with the same and projected from the end of the tube 10. By reason of the fact that the discharge end of the tube 10 is flattened or reduced as at 16 and the discharge outlet 17 is substantially V-shaped in plan the powder will be thrown in lateral directions as well as straight forward at the discharge end of the said tube. Thus the powder is scattered.

By reason of the fact that the bellows 1 is made up of two members having hinged sides connected together by the link 4 when one bellows member is discharging air through the recess 7 the other bellows mcmher is receiving air through the inlet 3 and vice versa. The valve disk 9 is made of cork or other similar light material and 0011- sequently as the air is expelled 'from one of the bellows members through one of the perforated plates 8 the air as it passes through the recess 7 will force the valve 9 against the other plate 8 and close the perforation thereof. By such an arrangement of bellows members a continuous blast of air may be caused to pass through the tube 10.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A powder distributer comprising a receptacle, a discharge tube communicating therewith, a bellows connected with the tube and consisting of duplicate members separated by a partition, said partition being provided with a recess which communicates at its ends with the interiors of the bellows members and a passage which joins with the recess at an intermediate point and a valve located in the recess and adapted to move to close the recess at opposite sides of the passage.

2. A powder distributer comprising a bellows, a tube attached thereto, a powder receptacle communicating with the tube, said tube having its discharge end flattened and its discharge outlet \lshaped in plan with the apex of the \l at the extreme end of the tube.

3. A powder distributer comprising a bellows, a tube attached thereto and having in its bottom a groove, a receptacle mounted upon the bellows, a funnel attached to the its bottom a groove and having receptacle and entering the tube and terminating above the groove thereof.

4. A powder distributer comprising a bellows, a tube attached thereto and having in its bottom a groove which is concaved longitudinally, a receptacle mounted upon the bellows, a funnel attached to the receptacle and entering the tube and terminating over the groove at a point between the ends thereof.

5. A powder distributer comprising a bellows, a tube attached thereto and having in in its top a section inclined from the bel ows toward said groove, a powder receptacle mounted upon the bellows, a funnel attached to the receptacle and entering the tube and terminating over the groove thereof.

In testimony that I claim the foregoing as my own, I have hereto affiXed my signature in the presence of two witnesses.
